Stamps From China And Possibly Japan.

Hi I have a few sleeves of a variety of Chinese and possibly Japanese stamps. I have no experience with these stamps, which is why I am not sure which is which!
Does anyone know of the best on line source for checking what these stamps are?
Thank you

Well, post a few pictures here! We can not really guess at something we can not see.

I'll have to do that tomorrow when I have access to the desktop, can't seem to do it via the IPad.

These will get you through 80% of your common Asian stamps:

The top symbol on the left, sort of like a rectangle with a vertical line through it, is China:

but you'll have to do a little more digging to be more specific.

If there is also this star, it is Republic of China:


The chrysanthemum flower (the circle design on the left) and/or the shape like a figure 8 on the far right are Japan:


edit: For some reason, my last images were not displaying...can an image file size be too small? Anyway, here is a Manchukuo block I'd uploaded previously, showing the five-petal orchid star, which is a dead giveaway for Manchukuo:

Nice work, Collin.
Your last two images are not showing, perhaps you have them similarly named, that prevents loading?

Dunno what the issue was.

Anyway, Elger, these will help you get them into piles, and you can use online references to further i.d. them from there.

Thank you very much! My eyesight is not the best at picking out these symbols! I have also finally I think got the images to work so will have a go and post them

At first glance China seems very complicated. So many overprints and regional issues. I just had a look at my catalogues and it made my head spin

Eiger, are you wondering if you have the stamps in your scans properly sorted out? I can help with the Japan

Bobby that would be very useful thank you! I think most are China but yes they can all be very confusing!

The following are Japan:

Scan 1 - the column of 4, top right

Scan 2 - all except middle stamp 2nd row, not sure what the large orange stamp is

Scan 3 - no Japan

Scan 4 - 1st row 1st stamp, 2nd row 2nd stamp, 3rd row 1st and last stamps, 4th row 2nd stamp

Scan 5 - the green stamp bottom right

Scan 6 - the ducks and geese at left

Scan 7 - no Japan (all China I'd say)

Scan 8 - the 3 vertical pairs and the single 30y

Scan 9 - 4th row, 2nd last stamp

Scan 10 - last row, 2nd last stamp

The large orange stamp at the bottom of the second picture is China Sc#169 from 1952.

Thank you so much Bobby that's amazingly helpful!

Thank you CJd !

I thought this would be an easy find with 1948 & Republic of China as being good indicators, no joy. Anyone?
